Maybe, maybe not.  What do you have going on?

It depends on "what" was inherited, and where it came from.

Someone else thought NOT and now I get to amend a return they filed themselves.

it depends - we all know that is too vague a question - what did they inherit? cash in the bank or an IRA? 

Posts like this make me think of that old Nilsson song-

everybody’s talking at me

I don’t hear a word they’re saying

only the echoes of my mind

I inherited my dad's ugly nose.

I was glad when his CPA told me it was not taxable.

You didn't get a second opinion?

I'd get a second opinion only if it was taxable.

For any opinion that was to my favor, I'd ride on the opiner's E&O insurance.

"I'd get a second opinion only if it was taxable."

 That's pretty much what anyone else would do.
